Diagnosis

The error message implies that the (SRM or gridftp) server closed the connection
without further details getting propagated to the user. Like in many cases,
one can learn more by trying a globus-url-copy directly:

$ globus-url-copy file:/etc/group gsiftp://some-SE.some-domain/tmp/test.$$
error: the server sent an error response: 530 530 No local mapping for Globus ID

When the user does appear in the grid-mapfile, it is likely that all the pool
accounts for the VO are taken. In that case the solution is to so add more pool
accounts and create corresponding empty files in /etc/grid-security/gridmapdir.
Otherwise see 530 530 No local mapping for Globus ID for other explanations.
